Product Description
The Adaptec 2251800-R is a robust RAID controller designed to provide high-performance storage connectivity and data protection for servers and workstations. Based on the Adaptec 3405 chipset, this card offers four external SAS (Serial Attached SCSI) ports, allowing for the connection of multiple SAS or SATA drives. The controller supports a comprehensive range of RAID levels, including RAID 0, 1, 10, 5, and 50, enabling users to configure their storage for optimal performance, redundancy, or a balance of both. Equipped with 128MB of DDR2 cache memory, the controller accelerates RAID operations, significantly improving read and write performance for connected storage devices. The PCI-Express x4 interface ensures a high-bandwidth connection to the host system's motherboard, minimizing potential bottlenecks and maximizing data throughput. This makes it suitable for demanding applications that require fast and reliable access to large amounts of data. The Adaptec 2251800-R is an ideal solution for environments requiring enhanced data integrity and performance from their storage subsystems. Its support for both SAS and SATA drives offers flexibility in drive selection, while the advanced RAID capabilities provide essential data protection against drive failures.
